Made for the New AQA GCSE Chemistry spec to be sat summer 2018.
Requires a practical of the precipitation of Lead Iodide from Lead Nitrate and Potassium Iodide as it's more interesting than the over-used Thermal Decomposition of a Carbonate.
This will need to be filtered and dried. I would personally recommend doing the practical straight away and then getting the filter papers to a drying oven, but if you have a large heating mantle, hot radiators or even a heated baking tray this should dry the sample sufficiently to test.
